Electric Boilers

There are occasions that fitting a gas condensing boiler is not an option because of building design, problems with running gas supplies or flues or, because of local or national planning and building regulations.


In these instances we believe that one of the best alternative products is an electric boiler and we recommend and install the GAH Electrastream with Tri-Core energy efficient heating technology.
